i put in for a return of my blue cloth cover and then realized the oasis was impossible to grip and hold without a cover, so i withdrew the request.
since then, living with the cover every day, i've gradually developed techniques for the situations where i know the connection will fail. it's worst for me when the cover is folded back and i want to fold it back over the front for carrying. unless you are very careful prying the bottom layer off the back it will slide off as if greased--as if there are no magnets there at all.
my workaround is to use my thumb at the bottom right and fold the bottom half of the cover upwards and then use that to leverage separating the whole thing. if you try to fold the whole cover it puts too much pressure at a bad angle and you simply push the magnets off the oasis.
i can live with it until someone (maybe amazon?) comes up with a better design. i ordered one of the $10 chinese ones from amazon and although they promised two-day delivery, it now says 44 days.
